IMPROVEMENT |N VCARRlAel-z-Bows.

Specification forming part of Letters Patent No. 215,476, dated May 2G, 1879 application filed October 30, 1878.

will be fully described in the body of the specication and specified in the claims, in connection with the accompanying drawings.

Figure l is a side elevation of a carriage provided with myJimproved bows. Fig..2 is

p a front or rear view or elevation of one of said bows. Fig. 3 is an enlarged detached longitudinal section taken on line A B, Fig. 2. Fig. 4 is a similarnsection taken on line C D,Fig. l. Fig. 5 is a detached longitudinal section of the bow and Slat-iron, showing the method of uniting them, and with the ferrule j formed as an integral part of Slat-iron d, and the central spur k shown screwthreaded. Fig. 6 is a section similar to Fig. 5, but showing ferrule j as formed separate from theslat-iron d, and a transverse rivet, 1, shown asa substitute for the screw thread on spur 7c. Fig. 7 is an enlarged transverse section taken on line E F, Figs. 1 and 2. Fig. 8 is an enlarged trans- .verse section taken on line G H, Fig. 1. Fig.

9 is an elevation of a vertical or lower member of my improved bowA fitted with the metallic coupling for connection with the bent portion, and also fitted with the slat iron for connection with the seat.

As heretofore constructed, carriage-bows have been bent of a single piece or bar of woody and ofcourse the fiber and strength thereof were the same throughout. This method of construction was open to the serious objection that the quality of timber which would permanently retain its form oneurve` at the bends was too soft and weak to withstand the strain when the top was turned dxown and the weight thereof wasexerted by a lever-like strain across the lower top-joint prop the ratio of such leverage being as the ratio` of the whole height of the top to the distance from m to a, the latter representing the fulcrum,

to counteract which long socketed Slat-irons form, while the vertical members which receive the principal strain are formed of the best quality of hickory, ash, lance-wood, or other suitable elastic woods.

In the drawings, a is the fbody, b the seat, and c the railkall which are only shown for the convenient description of the invention. d represents the Slat-irons, and e the vertical or lower members of the bows, while f is the head or bent portion thereof, which extends across the top and down the sides sufficient to form the bends and the connection with members e, as is plainly shown in Fig. 2.

The connection of members e and f may be effected by a variety of appliances@ but I prefer the method and means which I haveinvented, consisting in a scarfed joint of the two parts, as shown in Fig, 2 and by dotted lines in Fig. 4,.an inserted metal plate, h, and an inclosing ferrule, g, the latter encircling the several parts, as shown, the whole being secured together by pins t' i, which pass through the respective parts.

The Slat-iron d islformed with the usual eye 0 and shank p, while the upper end terminates in a central spur, Je, which may be screwthreaded for contact with the bow e, as shown in Fig. 5; on it may be y smooth, as shown in Fig. 6, in which case the `pin l, passing through `the ferrule, bow, and spur, as shown in Fig. 6, may bepsed as a substitute for the screw-thread. The ferrule j, to inclosebow e,

may be formed as a part of the Slat-iron, as

shown in Fig. r5, or" it may be separate, in which case it extends above and below the abutting joint, s, where the end of bow e bears against a shoulder` of the Slat-iron, as shown in Fig. 6; and when the separate ferrule is employed the slat-iron is formed with a second shoulder at t, Fig. (i, against which the ferrule j abuts with a iiushjoint. The ferrulej, when' formed separately, may, after the parts are finished and fitted, be soldered to the slatiron.

By forming the bow in three parts the members e may be finished and mounted with all the connecting-irons in large quantities as an article of manufacture, and then the bent head'may be fitted of such height and width as may in each case be desired, and by thus manufacturing the principal portion of the bows ready Iinished and ironed a material saving in cost may beleflected, While the quality ot' the work may be largely enhanced.

I do not, in this application, claim a slatiron formed with a socket -to receive the end of the bow, and with a flat blade to be inserted in a longitudinal slot or saw-kerf through the bow, as I am aware that such irons have been so employed heretofore; but

, What I doclaiin sl. A slat-iron, d, having a thin shoulder, t, to receive ferrule j, athicker shoulder, s, to receive the bow e, and a central spur, k, all substantially as specified.
